This OptionSet defines flags indicating the last activity taken by a ConnectionManager processing a given ConnectionConfigurationSet (and, in turn, on Connection configurations within). If the OptionSet is zero (no bits set), then no activity related to the given Connection in the given ConnectionConfigurationSet has been taken.
In this OptionSet, only one bit can be set except for the Error bit, which can be set with any of the other bits.
If the ConnectionManager supports the ProcessConnectionConfigurationSets Method, then the activities correspond to the described actions in the Method, but a ConnectionManager is not required to support the ProcessConnectionConfigurationSets Method. It could still have internal or application trigger activities that correspond to these actions.
The LastActivityMask values are formally defined in Table 184.
